SpaceX advances reuse efforts as recovery of two boosters nearly complete
Three launches, two recoveries, two coasts
Just over two weeks ago, SpaceX accomplished its most impressive feat of cadence yet, both launching and recovering two separate Falcon 9s in approximately 49 hours.
Two weeks later and two days after conducting a third launch in 13 days, residents of Los Angeles, California and Cape Canaveral, Florida both coincidentally reported that the two recovered boosters from the previous two launches had both gone horizontal and appeared ready for transport. After docking in Port Canaveral for the second time, Core 1029 was seen entering SpaceX’s LC-39A integration facilities on Friday. The booster on the West coast, 1036, was loaded aboard one of the company’s converted Falcon 9-carrying semi-trucks, likely for transport to SpaceX’s Hawthorne manufacturing facilities, or possibly on a direct route to McGregor, Texas for refurbishment and testing.

This is exciting for several reasons. Foremost, 1036 is a likely candidate for reuse, and SES-10 sets a firm precedent for this. The first commercial reuse of an orbital-class launch vehicle, Falcon 9’s second stage and SES-10 payload launched on a first stage that had flown five months before during the successful launch of Iridium’s first ten NEXT satellites.
Given the potential impact of failure on the adoption of reuse as a commercial standard, SpaceX likely approached the refurbishment of the vehicle with an end-goal balanced between perfection and realism. The orbit of Iridium’s NEXT constellation is the reason the booster was chosen for the first operational reuse: their low Earth polar orbits require Falcon 9’s first stage to undergo a smaller amount of heating and general hypersonic battering when compared with SpaceX’s more common commercial launches of geostationary satellites.

A sound example of the extremes of Falcon 9’s suborbital reentry heating can be found in the recovery of 1029, which launched BulgariaSat-1 to a supersynchronous transfer orbit. Noted before the launch by Musk over his favored medium, 1029’s recovery was expected to be the most energetic yet, and thus success was less than certain. The results of this additional heating were obvious, and keen observers rapidly noted that the most stressed of 1029’s aluminum grid fins appeared to be considerably deformed from the stage’s energetic return to OCISLY, completed melted through in places. Considering the debut of more robust titanium grid fins aboard the launch of Iridium-2 only two days later, the quasi-destruction of one of 1029’s grid fins was somewhat fitting. 1036’s titanium grid fins looked barely worse for wear after a landing that was also deemed aggressive due to Just Read The Instructions having to avoid bad weather just before the landing.

Stirring explorations of the limits of recovery aside, both boosters are now ready to be examined and refurbished ahead of one or even two additional launches. SpaceX’s willingness to use the booster recovered from the launch of Thaicom-8 has already established that the company has a certain level of confidence in the reuse of first stages that have suffered high-velocity recoveries. Thus, 1036 is nearly certain to be reused, and 1029 has a strong chance as well.

The hot recovery of 1029 further marked the first use of a remotely-operated recovery robot aboard OCISLY, and could be seen below the leaning first stage as it entered Port Canaveral. It appears that its first use was a success, and the robot will certainly have a busy future of remotely securing first stages after landing. Remote securing and safing will both improve safety for those directly involved in on-ocean recovery, but it is also intended to expedite the process in order to ensure that OCISLY is prepared to recover Falcon 9 as often as possible. SpaceX’s recent cadence accomplishment of three launches in 13 days drives home the reality that weekly launches are readily achievable for the company, so long as there are pads available and payloads to be launched.
Weekly recoveries for an ASDS like OCISLY would be extremely time-sensitive, given the need for at least several days to simply reach the point of landing in the Pacific, and the addition of rapid robotic alternatives for operations aboard the drone ships could make such a goal more achievable. With SpaceX’s land-based landing facilities in perspective, it is easier to imagine a close future with weekly launches and landings of both Falcon 9 and Falcon Heavy, and possibly the propulsive-landing Dragon 2 spacecraft further down the road.

A symbiosis of SpaceX fans and those familiar with the metal and chemistry have also led to fans speculating that the now-standard titanium grid fins may develop a subtle, golden patina of oxygenation after many reuses. Nothing could be more picturesquely symbolic of the successes SpaceX has had in their pursuit of reusable rocketry.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
